IMPROVEMENT IN WAGON-SPRINGS.

Specification forming part of Letters Pateut No. 169,323, dated October 26, 1875; application filed July 24, 1875.

To all whom it may concern:

Be it known that I, WILLIAM F. WHITNEY, of Poughkeepsie, in the county of Dutchess and State of New York, have invented certain Improvements in Springs for Vehicles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanyingdrawing, which forms part of this specification.

My invention relates to certain 'improvements in Springs for Vehicles operating on the torsion principle; and it consists in a novel arrangement and combination, whereby the application of torsion- Springs to a side-bar wagon is accomplished in a simple and economical manner, and a strong and durable Vehicle is produced.

In the accompanying drawing, Figure 1 is a side View of a Wagon embodying my invention. Fig. 2 is a bottom view of the same' Fig. 3 is an end view.

Arepresents the body of a Vehicle of the description known as a side-bar wago, and B B represent the side bars. G is a metallic bracket, having perforated lugs at its ends for securing it to the' under side of the body A by means of screws. About midway of the length of the bracket are two holes, one of which is round, and the other square. The square hole is for the reception of a square tenon on one end of a rod, E, and the round hole for the reception of the round portion of a similar rod. Four of these brackets are attached to the bottom of the body A, two near the front end, and two near the rear end, in parallel directions transversely to the length of the body. The rods E are made of elastic steel, and serve as springs by operating on the torsion principle. They are applied to the brackets by inserting the square tenon in the square hole of one bracket, while the round portion of the rod, near the opposite end, passes through, and works freely in, the round hole in the opposite bracket, projecting sligh tly beyond the same. Two of the rods are applied to the brackets on one side of the body,

and two more to those on the other side. The rods are so arranged that the square tenon of one rod engages with the square socket in the bracket toward the front end of thebody,

'and the square tenon of the other rod en gages outward at aboutright angles with the length,

so as to form arns F. The ends of these arms are attached to the side bars B, in any suitable manner. They are shown herein as attached by means of a pinjoint, f but they may be attached by means of links, or by arranging the ends of the arms to slide in sockets attached to the side bars. The ends of the side bars B are connected by flat or semielliptical Springs Gr G the rear spring Gr being attached directly to the rear aXle H and the front spring Gr having the bolster J attached to it.

The ends of the springs Gr Gr are shown herein as rigidly attached to the bars B B; but they may be attached by means of hinges or links, or in' any other maner which Will allow the bars to' rock when the body-A rises and falls. V

s shown herein, the brackets G are narrow, and the attachment of the rods E is close to the bottom of the body A, so that when'in its normal position the bottom of the body is on a higher level than that of the point of l attachment of the ends of the arms F to the side bars B 5 but the brackets U may be of such Width as to extend down Ward sufficiently far to place the body A in its normal position on a lower level than that of the bars B, in which case the arms F will be inclined upward from the bracket s instead of downward, as shown herein.

The rear aXle H and bolster J may be conaected 'by a reach, K. One or more of the rods E may be used on each side.

By the arrangement and combination above described the torsion-springsare applied to a side-bar wagon in a simple andeconomical manner, and a strong and durable Vehicleis obtained.
